1. Cold-rolled substrate color coated steel plate

The color plate produced from the cold-rolled substrate has a smooth and beautiful appearance and has the processing performance of the cold-rolled plate; however, any fine scratches of the surface coating exposes the cold-rolled substrate to the air, so that the exposed iron is quickly formed. Generate red rust. Therefore, this type of product can only be used for less demanding temporary insulation measures and for indoor use.

2. Hot-dip galvanized color coated steel plate

The product obtained by coating the organic paint on the hot-dip galvanized steel sheet is a hot-dip galvanized coated sheet. In addition to the protective effect of zinc, the organic coating on the surface of the hot-dip galvanized steel sheet also plays a role of insulation protection and rust prevention, and its service life is longer than that of hot galvanized sheet. The zinc content of the hot-dip galvanized substrate is generally 180 g/m2 (two-sided), and the galvanizing amount of the external galvanized substrate for buildings is 275 g/m2.

3. Hot-dip galvanized steel plate

On request, it is also possible to use hot-dip galvanized steel sheets as color coated substrates (55% AI-Zn and 5% AI-Zn).

4. Galvanized steel coated plate

The electroplated zinc plate is used as the substrate, and the product obtained by baking the organic coating is an electrogalvanized steel coated plate. Since the zinc layer of the electrogalvanized plate is thin, the zinc content is usually 20/20g/m2, so the product is not suitable for use. Make walls, roofs, etc. outdoors. However, because of its beautiful appearance and excellent processing performance, it can be used mainly for home appliances, audio equipment, steel furniture, and interior decoration.
